Where are you getting flights that cheap? Seriously, I'd've been to the US (from London) for a weekend already if the tickets I could find weren't 5x that.
Okay. But if I see someone state something as a fact, and I think that that something has no evidence for or against it, I'm going to call them out on it.
Will you let someone away with stating something as fact when it has some evidence for it, but more evidence against it? Or, more to the point, is your threshold of acceptable evidence the same for any proposition - so if I see a light in the sky enough times, I can say "it's a satellite, that's a fact" and "it's an alien, that's a fact" with equal validity?
I don't know where these numbers come from.
99.9% is an arbitrary figure; my actual level of confidence that this chocolate teapot doesn't exist is higher than that.
No. Just things that have no evidence for or against them.
You can't disentangle evidence from expectation; evidence is precisely that which causes you to update your expectation (and is meaningless beyond that). If you try to form probability theory without initial expectations, you get paradoxes. So we can only coherently define facts in terms of our final expectations, not the evidence, which is a vanishing intermediate value.
99.9% sure of what? If that was a "what if" scenario, then go ahead and state it as a fact.
Well, I'm more than 99.9% confident that the aforementioned chocolate teapot doesn't exist - and I suspect you are too. Yet you seem unhappy with calling that a fact.
The standard counter to that is: reasonable people would state as fact "there is not a chocolate teapot orbiting the sun at around the same distance as Neptune". It's not that we know anything to imply there isn't, it's that we have no possible reason to imagine such a thing would exist, and no evidence to even suggest it does.
The security concerns are also a non-issue as regular wallets and bank accounts are routinely stolen and money diverted.
For a regular bank account you get your money back when that happens.
The rise of better android handsets to overtake the iPhone was predicted again and again. And then it happened.
